and WALTER THOMA, citizens of. v the United tion.

The present invention relates generally to f phonographs or other soundreproducing machmes, and has more particularly reference v States, andresidents of Carlstadt,'. in the county 4.of Bergen .andState 4of NewJersey, have invented certain new and useful Phonographs, of which 'thefollowing. is a specificato a multi-record or repeater phonograph. suchas is' disclosed in Letters Patent No. 873,969 of December 17, 1907.

The main object of the inventionis the production of a machine,automatic through-.

ing period so that the rotation' of the record carrier will move thealinement device a surfivcient distance to position a new record afterwhich the locking devicelocks the'alinement device again.v In thepreferred'embodiment` the sound reproducing mechanism. isutili-zed to'release the locking device and to turn the record-carrier.

lnorder, however,.to allow for slight discrepancies, due. to lost.motion `or wenn. we employ (an intermediate driving mechanism foroperating the individual records which will compensate-for discrepanciesin size or positioning of the parts. i The intermediate drivingmechanism is carried on the free end of an arm which is loosely pivotedat the otherend. This intermediate driving mechanism rests on and is inengagement with transmission mechanism onthe driving shaft and isadapted 4to engage withtransmis'sion' mechanism on the records as theyare successively presented thereto.

The intermediate driving mechanism is thus held yieldingly in engagementwith its cooperating members whereby discrepancies in size and positionofthe parts are compensated for. Other features of construction willappear ,as the specification proceeds.

The thread follower has a tooth -21which enters the threads of the repeater screw.`

nose is allowed a certain amount of lateralpl'ay and has an'outwardlyturned projection 29 at its lower end.

, v When the sound reproducing mechanism' comes to the end of itsforward stroke, the trip on the repeater screw WilYengage withtheprojection 29 of the nose 27. The advance of the reproducingmechanism is .very gradual owing to the line threads of the feed screw,but the tri 3() need only engage the nose 2 1? very slight f since' t-helatter will be turned sidewise owing to-the fact that itisoo'sely-mounted and' the trip 3,0 will theref ebeable lo get agoodgrip under thepro je tion 29 thereby lifting the arm S and the soundreproducing mechanism. In case the trip does not engage the nose 27sufliciently the latter will merely sl'ip off without disturb theadvance of the reproducer and on the ext turn the latter will have movedforward 'auciently to enable the trip to properly en- ]gjge the"nose 27.lllhen the arm S is thus ted the thread follower 10 will slide into,yengagement with the thread 31 of there-i ,peater screw 'the weight ofthe parts causing the lever 19 toturn around its pivot to effect this.The .sound reproducer wvill now be Y moved ljffu and this motion willcontinuo until the `.;ead follower encounters the cam surface 32 of therepeater screw which will turn the follower around its swivel-and guideit into -the reverse thread 33 of the screw. Theadvance movement of thereproducer is thus commenced.vv During the return stroke of reproducerthe lower end of the tail 22 will have been-moved inward by ,the cam 33.This, however, has no effect on the Upon the forward stroke of therepro( ucer, the tail 22 will pass on the other side of the cam 33 andwhen the surface 34 is encountered the lower end of the tail 22 willmove. outward thereby causing the arms 24 to engage the v rojection 25of the follower 10 thereby ho ding it from turning on its swivel. Thetail can therefore move no further, inpendently, and the motion is thencontinued around the center 28 with the result that the follower ismoved sidewise off the repeater screw. This causes the arm 8' and artsscenes the reproducer to descend, whereby the follower 9 will engagewith the feed screw 12. On the end of the shaft or screw 12 is a gear35, and on the end of each record is a friction roll'36. 70

37 indicates an intermediate drivingimechanism mounted on the free endof the arm 38 pivoted at 39 on the bracket 40. This intermediate drivingmechanism consists of a gear 4,1 adapted to engage with the gear 35 75on the shaft 12, and a' friction roll 42 adapted to engage with thefriction roll 36- as they are successively brought into contacttherewith. Thegear 41 and roll 42 are mounted on the same stud 43 andmove together. The intermeshing teeth of the gears 35A and 41 should belong enough to allow the friction rolls 36 and 42 to bo always inengagement notwithstanding any"' `yielding movement of the intermediatedevice due to discrepancies in size or position of the parts. Theweight. of the intermediate driving mechanism will I usually besufficient to maintain contact, but if desired a spring 44 may beemployed. The rotatable alinement device and the locking 9.) meanstherefor are constructed as follows: Mounted on the stud 45 is theGeneva stop wheel 46 adapted to be turned at intervals h v theprojections 47 on the record carrier. lWhen the'carrier is tinerh'theprojection i7 9:, in engagementwith the Geneva stop wheel will turn itpart way, and the next projection 47 will turn it the remainder of thedistance until a lo: lhing device, to be described, acts lo lock theparts. Each step of the record cm2 100 rier is sullicient to bring thenext record to be played into engagement with its driving means.

43 is a locking pin adapted to engage with the notches on the Genevawheel asthev are 105 brought into alinement therewith. This locking-pinis carriedliy the pivoted lever 4U. This lever is adapted to be moved hv :1nother lever 50 pivoted atv 51 and provided with the two arms 52engaging the lever 4l). llc A. spring 53 bears against the lever lfiindserves to hold the locking pin 48 in engagement with the Geneva stopwheel; or serves to move the said pin into engagement therei with when anotchof the said wheel comes 11.5 intd alinement therewith. Means forreleasing the locking device arc provided taking the form of a trip .54,in this instance' carried by the sound reproducing mechanism. This tripis pivoted at 5.5 and has a stop 56 120 which holds it from movingioutof the way when it encounters the lever 5() on. the return stroke of thesound reproducing'mechanism. When this trip engages with the lever 50 onthe return stroke of the repro- 123 ducer the pin 48 will bc withdrawnfrom engagement with the Geneva stop wlieel, 1nd the record carrier isfree to turn the said wheel. On the forward stroke the trip 54 will rideidly over the-lever 50.

. shown) is in engagement with the recordv 4The voperation is asfollowsz' During the' sound reproducingperiod, the pin 48 is lockedwithl the Geneva stop wheel and the record carrier is prevented fromturning. .One of the records is rotated by the intermediate drivingmechanism, the stylus (not which is rotated, and the sound reproducing'mechanism is' advancing on its 4forward stroke by the thread follower 9engaging with the feed screw shaft 12. As the as ound re-` producercomes to the end of itsstrcke the trip willlengage the nose 27thereby'lifting the'sound reproducing mechanism up, bringe. ing thefollo'wer`9 lout of engagement with the feed screw shaft 12anddisengaging the sty lus from the record being played. By reason ofitsown weight the thread follower 10 will slide into Aengagement wit-h thethread 31 of will enter the cam groove 16 thereby turning 25.-

the repeater screw yand the sound reproducing mechanism will commenceits return movement. As it travels'back the tri 54 will releasethelocking device, and thepin 1.8

the recordcarrier and bringing another reco rd into engagement with itsindividual,

driving means; The locking device will then lock; the Geneva stop wheeland record carrier.V When the follower 10 reaches the cam' surface 32 inthe re eater screw the vmotion will be reversed an the sound reproducingmechanism will start forward again. On its forward stroke the tail 22`will pass on the outside of the cam 33 and when the -Surface 34 -isencountered the' tail 22 will clasp the follower 10 to 4prevent itfromturninggg,l after which the said follower will slide out of the thread33 thereby lowering 4the sound rew producing mechanism and causing thefollower 9 to engage with the feed screw 12' and the stylus to engagethe record to be played. It the pin 18 is removed the machine will notturn the carrier and the recordr already4 played will be repeated.Motion is imparted to the device by means ofthe pulley 57 on the mainshaft .12. From there the motion is transferred tothe repeater shaft bymeans.

of gears 58 and 59.- Whenin its downward position, the sound reproducingmechanism `is artially supported on the rail 60.
